Microsoft Windows, arguably the most popular operating system in use today, celebrates its 30th anniversary. Windows 10, the most recent iteration, doesn’t look a whole lot like it’s great-great-great-great-granddaddy, but some base features have persisted. You know Notepad and MS Paint? Yep, they’ve been around since the beginning. Installing Windows 1.0 required two rather large floppy disks, 256 KB of memory and a graphics card. (Please don’t say you don’t know what a floppy disk is, you’ll make us feel very old.) To the modern eye the beginnings of Windows look very, very clunky, but back then that was considered streamlined, especially when its predecessor, MS-DOS, only allowed for typed commands. No mouse pointing or moving windows for you! Looking for a trip down memory lane, or perhaps just want to see what all the fuss was about? Look no further.
